Why the slight levelling off? Experts could only speculate. The lead researcher on the CDC report, Stephen Blumberg, said it could be people are holding onto their landlines because it is part of their Internet and cable TV package. Or it could mean that we're hitting a ceiling for those people willing to completely abandon landlines, said John Palmer, a researcher at the Autonomous University in Barcelona, Spain, who was not involved in the report.
Some non-experts were surprised to hear that the change has slowed down a bit.
"We switched to only cellphones three years ago. The only time we would get calls on the landline was from telemarketers," said Justin Hodowanic, an 18-year-old college freshman from Atlanta.
Dan Warhola, 34, said he had a landline at his Columbus, Ohio, home but only because his security system was tied into it years ago when he bought his house.
"I couldn't even tell you what my (landline) phone number is," said Warhola, standing at baggage claim at Atlanta's Hartsfield-Jackson International Airport.
The CDC survey released Tuesday is based on in-person interviews in more than 21,000 homes during the last half of 2013. The researchers found:
- Not all homes have phones: About 3 per cent have no landline or cellphone.
- About 9 per cent have only landlines, and about 48 per cent have both. Five years ago, 17 per cent had only landlines, and about 60 per cent had landlines and cellphones.
- Younger people rely more on cellphones: Nearly two-thirds of people in their late 20s live in households with only cellphones. Only 14 per cent of people 65 and older use only cellphones.
- Men are a bit more likely to shun landlines than women.
- Poor adults are much more likely than higher-income people to have only cellphones.
- The Midwest is the most wireless region: About 44 per cent live in cellphone-only homes. The South and West were nearly as high. In the Northeast, 25 per cent live in cellphone-only households.
